The Sunway TaihuLight Supercomputer:
the Design of the Processor and the System

Haohuan Fu (The National Supercomputing Center in Wuxi)

Abstract:
The Sunway TaihuLight supercomputer is the world’s first system with a peak performance greater than 100 PFlops, and a parallel scale of over 10 million cores. In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators (NVIDIA GPU or Intel MIC), the computing power of TaihuLight is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements (MPEs) and computing processing elements (CPEs) in one chip. With 260 processing elements in one CPU, a single SW26010 provides a peak performance of over three TFlops. To alleviate the memory bandwidth bottleneck in most applications, each CPE comes with a scratch pad memory, which serves as a user-controlled cache. To support the parallelization of programs on the new many-core architecture, in addition to the basic C/C++ and Fortran compilers, the system provides a customized Sunway OpenACC tool that supports the OpenACC 2.0 syntax and supports the management of parallel tasks. This talk introduces and discusses the design philosophy behind both the many-core processor and the 10-million-core system. The application performance on both the processor and the system would also be discussed.

Haohuan Fu is the deputy director of the National Supercomputing Center in Wuxi, and leads the research and development efforts on Sunway TaihuLight, the current fastest supercomputer in the world. He is also an associate professor in the Ministry of Education Key Laboratory for Earth System Modeling, and Department of Earth System Science in Tsinghua University, where he leads the research group of High Performance Geo-Computing (HPGC). His research interests include design methodologies for highly efficient and highly scalable simulation applications that can take advantage of emerging multi-core, many-core, and reconfigurable architectures, and make full utilization of current Peta-Flops and future Exa-Flops supercomputers; and intelligent data Management, analysis, and data Mining platforms that combine the statistic methods and machine learning technologies. Fu has a PhD in computing from Imperial College London. He’s a member of IEEE. Since joining Tsinghua in 2011, Dr. Fu has been working towards the goal of providing both the most efficient simulation platforms and the most intelligent data management and analysis platforms for geoscience applications. His research has, for example, led to efficient designs of atmospheric dynamic solvers for both Tianhe-1A, Tianhe-2, Sunway TaihuLight supercomputers, and the reconfigurable computing platforms. The work based on reconfigurable technology can be both faster and more energy efficient than the Tianhe-1A and Tianhe-2 supercomputer, leading to a publication selected as one of the 27 most Significant Papers of the FPL conference in 25 years (27 out of 1765). The work based on the Sunway TaihuLight supercomputer manages to scale a fully-implicit solver to over 10 million cores, which won the Gordon Bell Prize of SC16.

ARM: scaling new heights

David Brash and Nigel Stephens (ARM)

Abstract: In 2011 ARM announced ARMv8-A which included the new 64-bit AArch64 execution state, a step change for the architecture. ARMv8-A is now well established across a wide range of devices spanning consumer and enterprise markets. Fujitsu’s 2016 announcement that Japan’s Post-K supercomputer would be based on ARMv8-A, followed by the disclosure of ARM’s next-generation Scalable Vector Extension (SVE) at HotChips, illustrates how the ARM processor architecture now scales from the smallest IoT devices to the largest HPC systems. This talk will focus on the evolution of the high-end ARMv8-A architecture, its recent enhancements for enterprise solutions, and its building momentum in high-performance scientific computing — all as part of an expanding collaboration between hardware, software and architecture partners. Key aspects of SVE will be outlined as well as the work to promote a thriving development ecosystem for tools, middleware and applications.

David Brash joined ARM in 1998 and took on responsibility for architecture program management in 2000. His responsibilities include chairing the Architecture Review Board, coordination of the development and delivery of the ARM Architecture specifications, along with enabling the supporting collateral needed for compliance and software development activities. The role also includes key partner engagement, evangelizing and encouraging early adoption of the ARM architecture and a vibrant tools, hardware and software development ecosystem. David started his career with Racal developing government and military communications equipment. He then joined Digital Equipment Company (DEC) to design backbone router and infrastructure products.

POWER9 Design Innovations

Jeffrey L. Burns (IBM Research, USA)

Abstract:  Cognitive computing has become a major trend, driving the rapid development of new applications and workloads. The upcoming IBM POWER9 implements several new features targeting these emerging cognitive workloads. Adding new and improved cognitive capabilities requires higher levels of performance and energy-efficiency in the IT infrastructure. The maturation of semiconductor scaling has made delivering these higher levels more challenging; reliance on scaling alone is insufficient. Because of these trends, innovation in design and architecture is crucial. Innovations are required to improve power-performance of processors, e.g., by increasing the ability to dynamically adjust operating points without compromising the reliability of the computations. Accelerators will increasingly be needed to improve the power/performance of systems. To enable practical accelerator integration, system architectures must be designed up-front to incorporate heterogeneous components such as today’s GPUs, as well as future accelerators for cognitive applications. In this presentation I will describe these trends, the POWER9 innovations that address them, and areas of research towards future systems.

Special Sessions (invited lectures)

TrueNorth: A Neurosynaptic Integrated Circuit
with 1 Million Spiking Digital Neurons

Yutaka Nakamura (IBM Japan)

Abstract: Inspired by the brain’s structure, we have developed an efficient, scalable, and flexible non–von Neumann architecture that leverages contemporary silicon technology. To demonstrate, we built TrueNorth, a 5.4-billion-transistor chip with 4096 neurosynaptic cores interconnected via an intra-chip network that integrates 1 million programmable spiking neurons and 256 million configurable synapses. Chips can be tiled in two dimensions via an inter-chip communication interface, seamlessly scaling the architecture to a cortex-like sheet of arbitrary size. The architecture is well suited to many applications that use complex neural networks in real time, for example, multi object detection and classification. With 400-pixel-by-240-pixel video input at 30 frames per second, the chip consumes 63 mW.

He received the B.S. degree from the Department of Mechanical Engineering, Waseda University, Tokyo, Japan, in 1985.

 

 

 

 

 

Low-Voltage Micro-Electrode-Dot-Array
Digital Microfluidic Biochips

Tsung-Yi Ho (National Tsing Hua University, Taiwan)

Abstract: A digital microfluidic biochip (DMFB) is an attractive technology platform for automating laboratory procedures in biochemistry. However, today’s DMFBs suffer from several limitations: (i) constraints on droplet size and the inability to vary droplet volume in a fine-grained manner; (ii) the lack of integrated sensors for real-time detection; (iii) the need for special fabrication processes and reliability/yield concerns. To overcome the above problems, DMFBs based on a micro-electrode-dot-array (MEDA) architecture, and fabricated using a TSMC 350 nm process, have recently been demonstrated.
This presentation will first describe a biochemistry synthesis approach for such MEDA biochips. This synthesis method targets operation scheduling, module placement, routing of droplets of various sizes, and diagonal movement of droplets in a two-dimensional array. Simulation results using benchmarks and experimental results using a fabricated MEDA biochip will be presented to demonstrate the effectiveness of the proposed co-optimization technique. Finally, the presentation will describe an efficient built-in self-test (BIST) solution for MEDA biochips. Simulation results based on HSPICE and experiments using fabricated MEDA biochips will highlight the effectiveness of the proposed BIST architecture.
